Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair cutters with interchangeable cutter head assemblies fail to adaptively adjust running speeds according to the different functions of the assemblies, leading to a poor user experience.
Innovation Solution
A hair cutter with a cutter head assembly identification structure that includes a detection assembly to identify the type of cutter head assembly and control the drive assembly's output speed based on the cutting type, using a light-transmitting plate and infrared technology to communicate with a control board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a main body is designed to accommodate multiple cutter head assemblies with different functions, then the versatility and cost-effectiveness improve, but the system cannot adaptively adjust running speeds according to different cutter head requirements, leading to poor user experience
Solution Approach 1:
The patent implements a feedback mechanism where the cutter head assembly includes an identification part (e.g., light-transmitting plate with specific transmittance) that communicates its type to the main body through an identification channel. The detection assembly detects this identification signal and feeds it back to the control board, which then automatically adjusts the drive assembly's output speed to match the specific cutter head's requirements, enabling adaptive operation without manual intervention
Solution Approach 2:
The patent replaces manual speed adjustment mechanisms with an automated optical detection and control system. Instead of requiring users to manually select or adjust speeds for different cutter heads, the system uses optical identification (light-transmitting plates with different transmittances) and electronic control to automatically determine the cutter head type and adjust the drive speed, substituting mechanical/manual operations with automated sensing and control
2Quantity of substance
If a single main body is used with multiple cutter head assemblies, then the quantity of devices needed reduces, but the complexity of the identification and control system increases
Solution Approach 1:
The patent introduces an intermediary identification system consisting of light-transmitting plates with different transmittances attached to different cutter head assemblies. These plates serve as intermediaries that carry identification information through the identification channel to the detection assembly, enabling the main body to distinguish between different cutter head types without requiring complex direct communication mechanisms between the main body and each cutter head
Solution Approach 2:
The patent uses optical copies (light-transmitting plates) to represent different cutter head types. Instead of requiring the main body to directly sense complex physical or electronic characteristics of each cutter head, the system uses simplified optical copies with different light transmittances that replicate the essential identification information, reducing the complexity of the detection and control systems
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a single main body to operate multiple cutter head assemblies efficiently by adjusting speeds optimally, enhancing user experience and reducing the need for multiple devices.
Implementation Method 1
the identification part may be or may include a light-transmitting plate connected to the side or bottom of the cutter head assembly facing the main body
Implementation Method 2
An infrared transmitter is provided on/adjacent to one sidewall of the identification channel, and a photoelectric receiver is provided on/adjacent to the other sidewall. When the cutter head assembly is connected to the main body of the hair cutter, the light-transmitting plate on the cutter head assembly penetrates the main body when inserted into the identification channel through the channel opening; the infrared transmitter emits infrared light
Implementation Method 3
the infrared transmitter emits infrared light that passes through the sidewall and light-transmitting plate of the identification part and is received by the photoelectric receiver
